CORN-PLANTER CH'ECK-ROWE'R.

SPECIFICATION forming part of Letters Patent No. 244,178, dated July 12, 1881.

Application filed December 3, 1880. (Model.)

To all whom it may concern:

Be it known that I, GEORGE W. BROWN, 'a citizen of the United States, residin gat Galesburg, in the county of Knox and State of Illinois, have invented certain new and usefulImprovements in Corn-Planter Qhe'ck Row-ers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the-accompanyin g drawings, and to letters or figures of reference marked thereon, which form a part of this specification. My invention relates to that class of checkrower attachments to corn-planters in which the power for actuating the seed-slides is obtained by contact of the moving machine with knots or tappets on a fixed check-row wire or cord; and the nature thereof consists in eertain improvements in the construction and combination of parts of the devices which receive motion from the check-rowchain and impart motion to the seed-slides of the planter, and also in improvements in the construction of the check-row chain, hereinafter described.

In the accompanying drawings, which illus- V trate my invention, and in which the similar letters used as marks of reference apply to the like parts in all the figures, Figure 1 is a perspective of a construction embodying my invention. Fig. 2 is a top plan of the parts beneath the upper plate. Fig. 3 is same plan as Fig. 2, but the parts shown in different relative positions therefrom. Fig. 4 is a sectional elevation in line at m in Fig. 3. Fig. 5 is a perspective of the lower oscillating deflector. Fig. 6 is a perspective of the upper oscillating deflector, bottom side upward. Fig. 7 is a perspective of one of the oscillating arms. Fig. 8 is a sectional plan of a knot, showing its attachment to check-row chain. a

The construction and relative arrangement of the parts of the improvement and the ad- 5 jacent parts of the general machine in which said improvements may be incorporated are as follows:

Letter A represents a bar common to this class of check-rowers, which bar extends across 50 the planter and has fixed to each of its projecting ends a base-plate, B, each of which baseplates-carries a =set'o'f the working parts of my improvement, on'e'only of which is shown in the drawings and hereinafter described, as the other is atl'uplica-t'e thereof in all essential fea- 5 5 tures.

O O are cam-arms, duplicat'esof each other, and each bent so that their ends 0 are about at right angles with their ends 0'1. The camar ms O O are jour-naled at their bends c' to the plate B in such manner that the heads E E on their ends 0 respectively are confronting each other and at a short distance from each other. The confronting faces of the heads E E are convex, and each has a longitudinal groove, e,te'rn1inated at its rear end by a semicircular shoulder, c, with a semicircular groove, 6, in itsouter side, as shown at Fig. 7. Theends c of cam-arm's O G are connected by a link, 0', and one of them has a stud, f, to which one end of a rod or link, F, is connected, which extends across'the-planter, and is connected at its other end with a similar oscillating arm connected with the similar set of devices at the 'otherend of the bar A. (Not shownin the draw 7 5 ings.) The link F is also connected with the seed-slide-opera'ting bar. (Not shown.) I G is an oscillating check-row-chain deflector, formed of a lower plate, G, pivoted at its rear end, at g, to the plate B, and an upper plate, G, supported a short distance above it on studs H H. The opposite sides g of the plate G are concave, and a rib or projection, g, extends lengthwise on its upper side. The rib g has a forward pointed end formed by inclined 8 5 converging faces g 9, and its rear end is also tapering, as shown in the drawings. The plate G is divided lengthwise, or formed in two parts, with a space, h, between them, and each part has a rib, g, projectingfrom its lower side down to a short distance from the rib g, the contours of the sides of which ribs correspond exactly with the contours of the sides of the rib g on the lower plate, G, which sides are immediately beneath each upper rib, g, 5 respectively, so that the upper and lower ribs, 9', form a deflector, as hereinafter described, located interjacent or between the heads E E. The plate G extends over and rests close above the heads E E. g

I l are lugs or studs projecting upward from the plate A in rear of the studs H.

J J are wings or flanges projecting upward from the plate A, and located with their converging ends close in front of the plate G, and have a recess, j, between their connected ends.

K is the ordinary check-row-chain guidepulley, located adjacent to a guide-arm, L, on the forward end of the plate A.

M is the check-row chain or wire, formed of sections on of wire, with a spherical or otherwise suitably-shaped knot or tappet, N, secured at the union-s of each section m with the adjacent section, as follows: The tappets N have a central hole, a, with enlarged ends, it. The adjacent ends of two sections of wire at are passed through the holes a and each coiled upon the other and the coils m drawn within the enlarged ends it of the holes a, as shown at Fig. 8, thus securing the ends of the wire sections to each other and the tappets at the union of the sections.

To commence planting, the wire M between two of the tappets is placed over and parallel with the space It between the two sides of the plate G, so that it may drop down and between the heads E E, and either at one side or resting on the lower rib, g, and in the recess 9. Supposing the heads E E now to be in the relative positions shown at Fig. 2 and the machine to be moved in the direction shown by the arrow, the first tappet, N, will be guided by the recess j and deflected bythe faces 9 on the upper and lower ribs, 9, and thrown into the grooved adjacent side of the head E, where it will strike the shoulder e and force the head E backward, swinging the cam arm 0, and by means of the link 0 swinging the cam-arm G, and thereby throwing the head E forward into the position shown at Fig. 3. The convex cam-face of the head E, in swinging forward, as last described, came in contact with the concave side 9 of the plate G, and thereby swung the plate G over to the position shown at same figure, and in such position that the face 9 of the ribs 9 will deflect the next succeding tappet so as to come in contact with the shoulder e of the head E and swing it backward, and thereby swing the head E forward again, ready for the action of the next succeeding tappet. The cam-face of the head E, in swinging forward,will swing theplate G back to the position shown at Fig. 2 by acting on its adjacent concave side. In swinging the head E backward the shoulder 6 will be thrown away from the rib g, and the wire M, being held from deflection with it by the stud I, will release the tappet from the shoulder 6 when the head E has reached the end of its throw, as limited by a stud, H. The tappets are released from the head E by the other stud, H, in a similar manner to the release from the head E. While the tappets are in contact with the shoulders 0 the wire of the check-row chain will rest in the groove 0. The wire of the check-row chain may move laterally as required between the upper and lower ribs, g. At every throw or swing of the cam-arms O O a movement will be' given the corn-planter seed-slides in the evident manner.

The check-row chain is stretched and the planter moved in relation to it in the ordinary manner, and need not be described here.
